CHICAGO, Dec. 13 (UPI) -- Anyone either age 50 or older, a history of smoking, obesity or a sedentary lifestyle should get a medical clearance before shoveling snow, doctors say.
Health experts at Northwestern Medicine's Bluhm Cardiovascular Institute in Chicago say physical activity such as shoveling raises heart rate and blood pressure, while cold temperatures reduce circulation to the body's extremities, so shoveling heavy snow in frigid temperatures can cause heart attacks.
